simulation ltspice

Hello everyone! Due to very low leakage current requirements, in nA range, and high voltage of around 100V, I cannot use normal ESD diodes for protection. So, I was looking at Avalanche transistor and wanted to use its collector-base junction as a ESD diode. I came across FMMT41x series of...

Hi, Hope everyone is doing great. I am building a circuit in LTSpice using the inverting configuration of the LT1028 operational amplifier. The input signal provided is 0.7 Vp, which is applied to R1 (5M ohm). For the feedback resistor (Rf), I am using my biosensor, whose impedance varies from...

would i have to connect a voltage supply to the input of the logic gate(output of comparator)?

I drew this circuit in LTSpice. I want to find DNL (Differential Non linearity), INL (integral non linearity) and THD ( Total Harmonic Distortion ) of the circuit. Please Help me. Its very urgent!!

Hi everybody, I'm a beginner with LTspice, so I'm sorry if my question is related to some basic knowledge that I don't know..any help is really appreciate!! I can't solve a problem with my circuit in LTspice: I have this error "singular matrix check node vout+" and I don't know what to do. I...

Hi all, I was trying to simulate the schematic seen in the following video: I don't understand why I can't get it to work. Does anyone have any ideas? Thanks

Hi, Thank you for your time in advance. I tried to simulate the action of a silicon photomultiplier(SiPM) using a second-order RC circuit and it worked well. The output voltage is named sipm and is shown as the red curve in the plot pane. Then I wanted to connect this output to a voltage...

Hello, Im looking for anyone that may be able to help me figure out why my Colpitts oscillator simulation isn't generating a waveform. This circuit has already been tested as a prototype and generates the desired waveform, but for some reason, it won't do it for the simulation. I suspected that...

Hi, An initially charged capacitor in a resonance circuit undergoes periodic voltage reversal (blue line), as shown below: A possible circuit to address this problem uses 2 capacitor banks & switch modules, as shown: C₁ and C₂ represent metallized film capacitor banks of equal capacitance...

I have designed a subcircuit by writing code and did a transient simulation. How would I know the power consumption or energy consumed by the circuit? Thank you. santlal prajapati

How does LTspice search for symbols and subcircuits? Is it different for automatically generated symbols and Out of the box symbols? I ask because I ran into an error message that states "Could not open library file "C:\users\*****\Documents\***etc". This was when I tried to run a new project...

I am not sure if I simulated correctly the Q = 84 for 1.575 GHz in LTspice for Coilcraft inductance 0402DC 8.2 nF Model libraries for LTspice are here (lower right corner). The next question is if it is possible to replace the trace expression to plot by function i.e. to define the expression...

I'm trying to simulate a chaotic circuit involving a single equilibrium point, but when I try simulating the circuit I'm getting an error with one of the multiplier blocks (AD633) regarding the time step being too small. I need my simulation to run for around 100-200 sec for getting the desired...

I am simulating Recurrent Neural Network(RNN) with Ltsipce simulator. There, I need to store intermediate output and use it later. Can you please suggest me how can I use memory in Ltspice ? Or any link that will help me?

First of all, thanks for reading this, I tried to replicate this research as my project (not aim to publish or anything just for study purpose) Reference: https://www.iasj.net/iasj/download/ceca8bad4ee05e7c Now I tried to guess and do what I can do about this circuit and the result is this...
